A cover member 11 having apertures corresponding to the four locations ABC1, Al, B1, Cl, is positioned over the gauges A, B, C so that the ends of the connecting wires terminate beneath the apertures, means being provided, e.g. solder, for securing the ends of the wires there and for connecting leads from a meter to the wire ends. As described, solder is applied via the apertures so as to connect the cover 11 to the base 10 and provide projecting solder points A2, B2, C2 to which leads 16 may be attached from a meter. The assembly may be adhered to the member 15 by adhesive 12 on the base 10 or by this adhesive together with that provided on a portion of cover 11 that overlaps the base 10. The cover and base may be circular. The cover may be transparent to allow gauges A, B, C, or co-ordinates on the base corresponding to the directions thereof, to be seen. Alternately appropriate markings which may comprise the positions of solder points A2, B2, C2, may be provided on the cover. Gauges A, B, are preferably at right angles with strain gauge C between them. The unitary assembly may be employed in a method of determining the internal stress of the member 15 having a biaxial internal stress condition, or a triaxial stress condition in which one of the three principal stresses is in the vicinity of a free surface of the member, which method is claimed in claim 4 of Specification 1351859.

A railway goods vehicle comprises a single shell swingable roof 1, Fig. 1, having at each of its ends a support 1a mounted through a bearing 2 on the corresponding end wall 3 of the vehicle. The roof may be opened from either side of the vehicle through the agency of a hand wheel 4, a chain 5 and chain wheel 6, the latter having coaxial therewith a chain wheel 7 engaged with a chain 8 guided in an arcuate channel 9 and secured at its ends to the associated vehicle roof support 1a. An hydraulic cylinder is pivotally connected at 11 to the end wall 3 and the rod of a piston movable in the cylinder is pivotally connected to the support 1a at 13. The cylinder below the piston is connected by tubes 14, 15 to hydraulic accumulators 16, 17, carried on the wall 3. Each accumulator has a flexible diaphragm 18 and the space above the diaphragm contains gas under pressure. Hydraulic liquid fills the spaces below the diaphragms, the tubes 14, 15 and the space below the piston. Clearly, when the roof is swung to one side or the other, energy is stored in the accumulator to assist the subsequent closing movement of the roof. In another embodiment in which the roof is operated hydraulically as described with reference to Fig. 2 (not shown), the accumulators 16, 17 are movable with the hydraulic cylinder, and the space above the piston is oonnectible through a control valve either with an hydraulic pump or an hydraulic reservoir, the pump being hand-operated but may be operated by an electric motor. The pivotal connection between the piston rod and the roof end support is laterally displaceable on the latter. If desired, there may be only one accumulator connected to the cylinder. Reference has been directed by the Comptroller to Specification 829,473.

Abstract: 1346065 Measuring thrust J S SWEARINGEN 27 Dec 1970 [7 Jan 1970] 41366/70 Heading G1W A thrust bearing includes a chamber 24 between opposed thrust surfaces on the rotor part 14 and the stator part 12, a conduit 16 for supplying lubricating oil via a restrictor 22 to the chamber 24, and a conduit 28 for monitoring the pressure in the chamber 24. The pressure in the chamber 24 is compared with the pressure in the chamber 25 of another thrust bearing Fig. 1, with the pressure of the oil in the chamber 11a, or with the pressure of the oil at a point prior to entering the chamber 24,  to produce a measure of the axial thrust on the bearing. This measure of thrust may be used either manually or automatically to vary the axial thrust on the shaft by adjustment of valve 43 (see below). As shown in Fig. 1, the shaft 11 of a centrifugal compressor 10 is positioned axially by opposed thrust bearings 14, 15. The thrust chambers 24 and 25 respectively are supplied with oil via similar restrictors 22 and 23 respectively, and the differential pressure between chambers 24 and 25 is determined as a measure of axial thrust by a differential guage 30. The compressor comprises a rotor 31, a stator, and seals 38 and 39 therebetween. The pressure in chamber 40 caused by air leaking past seal 39 is controlled by adjustment of valve 43. The arrangement may be such that valve 43 is adjusted automatically according to the differential pressure determined by gauge 30 to control the axial thrust or shaft 11. Compressor 10 may be replaced by a centrifugal pump, a turbine or a turboexpander.

Abstract: 985,396. Clearing and indicating yarn faults. LOUIS NEWMARK Ltd. Nov. 1,1962, No. 41439/62 Headings D1F and D1J. [Also in Divisions G1 and H3] The invention relates to apparatus for the detection and removal of faults in yarns and comprises a photo-electric yarn clearer unit of the type in which a photo-cell 1 detecting the obscuration of light by a running yarn Y under investigation is differentially connected to a similar photo-cell 2 detecting obscuration of light by a stationary reference piece of yarn, wherein the resultant output of the unit is directly coupled to the input of a transistor amplifier whose load circuit includes means such as a tunnel diode TD1 for controlling the operation of succeeding stages, such as a yarn cutter unit 5, of the yarn clearer unit without excessive drift of the amplifier. In the embodiment shown the output of the two photocells 1, 2 is connected to the base of a transistor T1 whose collector is connected in series with a resistor R2 and a tunnel diode TD1. The quiescent point of T1, is set by the bias voltage obtained across a potentiometer VR1, which is such that the tunnel diode TD1 switches to point Iv/Vv (Fig. 2) when both cells 1, 2 receive equal illumination. By means of an adjustable shutter (not shown) controlling the light reaching the cell 2 the light is obscured until this cell provides an opposing bias voltage which holds the current amplified by T1 and passing through the tunnel diode TD1 to a point below that at which it will switch i.e. below Ip/Vp (Fig. 2) so that when there is an increase in yarn diameter the illumination incident on the cell 1 decreases causing the current through the diode TD1 to rise to point Ip and then in accordance with the negative resistance characteristic of the diode, to switch rapidly to point Iv/Vv, the application of the voltage Vv to NPN transistor T2 causing it to conduct violently. This causes the collector voltage to approach the full negative supply voltage with respect to conductor 3, which voltage is applied to a transistor T3 to provide a low impedance input to a transistor current amplifier T4. The amplified current is applied to a power transistor T5 to cause conduction therein and subsequent energization of a coil S1 of a yarn cutter unit 5. A resistor R6 and a capacitor C2 and the filament resistance of an indicator lamp 7 provide a high current to the coil S1 at the moment of switching of T5 to cause rapid operation of the cutter 5. Specification 716,370 is referred to.
